SPECIFICATION forming part of Letters Patent No. 784,119, dated ll'l'areh 7, 1905,

Application filed February 25, 1904. Serial No. 195,201.

To [nl] whom, if; ln/(ny coll/carla:

Be it known that we, OLor A. NonLUND and WILLIAM K. WAKENHUT, residents ol,I lV illiamsport, in the county of Lycoming and State oi' Pennsyl Vania, have invented certain new and useful Improvements in Ice-Creepers; and we do hereby declare the following to be a full, clear, and exact description oi' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in .ice-Creepers, the object of the invention being to provide improved construction of Creeper and improved means for securing the same to the heel of a boot or shoe; and it consists in certain novel features ot' construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

fln the accompanying` drawings, Figure l is a bottom plan view illustrating our improvements secured to the heel of a boot or shoe. Fig. 2 is a view in longitudinal section. Fig. 3 is a view in plan, showing the device in its unlocked position; and Figs. 4 and 5 are views oi' a modiiieation.

l represents a sheet-metalu plate oi' the general shape oi'I boot or shoe heel and having-integral prongs 2 at its straight edge adapted to be forced into the forward edge ol the heel by our improved clampingmechanism, which will now be described.

An approximately S-shaped lever 3 is pivotally secured at one end by a rivet 4 to the plate 1 near its center, and the outer end olI the lever is twisted and bent at right angles, forming a finger-hold 5 at one edge of the plate to facilitate manipulation of the lever 3.

6 represents a slotted bar having' a clamping-prong 7 at one end to engage the rear edge oi' the heel. A headed rivet 8 in plate 1 is located in the slot 9 of bar 6, and the latter has secured therein a pin l0, one end ot' which is located in a slot l1 in plate l, and the other end projects below bar 6 and is adapted to enter any oi a series of holes l2 in a flat spring-link .13, pivotally secured to lever 3 at its bend nearest its pivotal point. lt will be seen that by raising' spring-link i3 lrom pin 10 the bar (i can be moved to locate the pin 10 in another of the openings l2, and thereby adjust the clamp to lit other sizes oil heels.

The plate l is shown provided with iour calks or points ist, although any desired number may be employed, one ol" which being preferably located to 'form a stop'liorthelever 3 in clamping position, and said lever 3 and plate l are made with openings alined when the lever is in clamping position to receive a screw, tack, or other like securing' device 15, which is driven into the heel to permaiiently secure the creeper in place. This screw or tach l5 is only desirable where the creeper is to remain on the heel for an indelinite period and is not used where the creeper is to be often removed and replaced.

ln Figs. at and 5 a modilication is shown in which but three callts are employed, and the prong 16 of sliding bar 6 engages the inner edge of the heel, a prong 17, integral with plate l, engaging the rear edge oi the heel. The bar (i in this Vform has the spring-link 13 pivotally connected thereto, and the lever 3 carries the pin Yl() to enter any ol the holes l2 in said link.

The operation of both forms of creeper is as follows: The lever 3 is thrown toits extreme open position and plate l placed against the heel, with the prongs oit the plate and sliding bar 6 against the sides` thereof. The lever 3 is then Vforced to its locking position, which movement draws inward the sliding bar 6 and clamps the heel between thc lixed and movable prongs, and when the lever is moved far enough to swing its connection with the spring-linl 13 past the line ot' its pivot the several parts will be secured in such position.

Slight changes lnight be made in the general t'orni and arrangement oi the several parts described without departing Vfrom the spirit and scope elAl our inventirm, `and hence we do not restrict ourselves to the precise details set lorth, but consider ourselves at lib erty to malte such slight changes and alterau tions as Fairly fall within the spirit and scopo ol our invention.

llaving 'Fully described our invention, what We claim as new, and desire to secure b y Letters Patent, is-

l. In an ice-Creeper, the combination with a plate having a fixed prong, of a sliding bar having a prong, and a lever pivoted to the plate, said bar and lever constituting' movable members on the plate, and a link pivotally connected to one of said members and having a series of openings to receive in any of them a pin or projection on the other movable member.

2.' 1n an ice-Creeper, the combination with a plate having a fixed prong, of a sliding bar having a prong, a lever pivotally connected With the plate, said sliding bar and lever constituting movable members on the plate, and a spring-link pivotally connected at one end to one member and having a series of openings at its other end to receive in any of them a pin or projection on the other movable member.

3. 1n an ice-Creeper, the Combination with a slotted plate having calks thereon and a prong at one end, of a slotted bar at the other end of the plate having a prong thereonga headed lug or rivet on the plate and projecting through the slot in the bar, and a pin on the bar projectinginto the slot in the plate and the other end of said pin projecting below the bar, a fiat perforated spring-link pivotally connected at one end to the bar by means of the pin entering one of its perforations, an S-shaped lever pivotally secured at one end to the plate, and pivotally secured to the spring-link at the bend in the S-shaped lever nearest its pivotal point.

4. In an ice-Creeper, the combination With a plate having a prong thereon, of a sliding bar carrying a prong', an S-shaped lever pivoted to the plate, a link connecting the lever and sliding bar, and said plate and lever having openings therein which aline When the lever is in its locked. position to receive a screw or like device projected through the alined openings into the heel or' a boot or shoe and permanently secure the Creeper in place.

In testimony whereof We have signed this specification in the presence of two subscribing witnesses.
